AThe invention ,relates .to a novel and improved method of packing loose particles of food, such for example, as raisins, nuts, hard and improved steps `in the formation of a package for packing loose particles of food,

and the like.

The package formed by the novel and improved method is characterized by being comof said backing being that of the finishedv pact and neat in appearance, and all of the walls of which except one wall thereof being transparent whereby the contents thereof may be readily inspected from the outside thereof, and by having a withdrawable-flap or apron, which is adapted to 'facilitate the dispensing of the contents ofthe package therefrom. This results from the novel method employed in packaging the contents.

v According to the invention the package is formed from a single piece'of transparent material of any'v desired shape, such for example, as glassine paper, or the like, and a stiff cardboard backing, the shapeand size package. The piece of transparent material has formed 'therein a pocketJor depression, the size and shape of which -is that of the finished package, the loose particles of food are then placed within said pocket, and one corner or side of said transparent material is folded over said particles of food. The stiff cardboard backing is then placed over said food. particles and the folded over corner, and the remaining corners or sides of said transparent sheet are then folded over on said stiff backing, thus completely and fully enclosing said food particles. The, lpackage may then be sealed by securing the said folded over corners or sides' of said transparent sheet to said stiff back, which may be done in several well known ways. have found, however, the following method for securing the folded over corners to the stiff backing to be the most advantageous. I provide a label or seal gummed on the inner side, which label or seal isA of the same size and shape as the stiH back, and is appiied thereto to seal the package.

This application is a division of my application tiled August 2,4, 1927, Serial No. 215,004.

To these and other ends, the nature of which will be readily understood as the invention is hereinafter disclosed, said invention consists in the improved method hereinafter more fully described, illustrated in the accompanying drawings, and more vparticularly-pointed out in the appended claims.

In the accompanying' drawings forming a part of this application and in which like numerals designate likelor similar parts throughout the several views:

Fig. 1 is a top plan view of the *wrapper employed in carrying the invention into effect, said wrapper being shown in position on a form and ready for the first step Vin the series of steps informing and filling the package; I A 1 l Figs. 2 to 7 inclusive, illustrate the succes-v sive steps of filling and forming the package; 1

Fig. 8 illustrates the finished package; and

Fig. 8, illustrates the lfinished package; and

the upper flap pulled out for assisting in dispensing the contents from the package.

In carrying the invention into edect, a package is produced whichk is filled with loose particles of food, such for example, as raisins, nuts, hard candies, a mixture of nuts and raisins, and the like, one wall of which package is relatively stift', and the remaining walls of which are formed yfrom a single piece or sheet of transparent material, such for eX- ample, as glassine paper, or the like, said transparent material having -three corners or sides thereof folded over and secured to the outer'side of said stiff wall, and the remaining corner or yside being disposed between the contents of the package and the inner side of said stid wall, whereby the said last-mentioned corner or side may be pulled out and assist in dispensing the contents from the package.

In the method contemplated of forming the package, a `wrapper 10, of transparent material, such for example, as glassine paper, or the like, is depressed in its central portion to ferm a pocket or depression' 11, therein,v

. of which is that of the vthickness of the 1in-- the shape of said pocket being that of the de- 11, may be formed in one of several' ways,- however, I have found the following method of forming the pocket 11, to be the most practical. I employ aframe or member 14, pro.- vided. with a recess or'depression 12, the size and shape of which is that ofthesize and gummed on the inner side, and is applied to shape of the finished package, and the depth ished package. The size and shape of said member 14, being sufiicient to accommodate the wrapper 10, thereon, as shown in Fig. 1. A. member 15, provided with a plunger 13, mayl be hinged to said member 14, at one side thereof, the member 1-5, being adapted to be swung to bring the plunger 13, into the recess 12, as shown in Fig. 2, the-shape and size of said member 15, being preferably the same as that of the member 14, for a purpose lto be hereinafter described. l

The first stepA then in the filling and forming of the packageis to place the wrapper 10,

on the member 14, the said wrapper being centered over the depression or recess 12, as shown in Fig.' 1.` The member 15, is then swung about its pivot to bring the plunger 13, to its lowermost` position in the recess 12,

'depressing the centLial portion of the Wrapper 10, to form the pocket 11 therein, the corners or sides of the wrapper being' held flat against the upper surface of the member 14,

lby the member 1'5, upon which the plunger 18, is mounted,'thusthe turning or curling up of the corners of the wrapper is prevented in the Aformation of the pocket or depression in the wrapper.

It will be noted that during the downward movementof the plunger 13, in forming the depression or pocket 11, the corners or sides of the wrapper 10, are free to move inwardly towards the depression in vthe. member 14. Thus the danger of the paper or wrapper 10, tearing during theformation of the pocket 11, is eliminated.

--When the pocket has been formed and the plunger withdrawn, the loose particles of food 16, are'then placed in the pocket and tamped down', said pocket being filled just up to the level of the top thereof, as shown in the drawings. Then one of the corners or sidesv of the wrapper 10, the corner17, for example, is folded over and disposed on top of the vfood particles as shown in Fig. 4. The

next step is to place a stiff sheet of cardboard 18, or the like, directly on top of the food par-l ticles 16, and of course overthe folded over corner 17, of the wrapper, as shown in Fig.

5, the size and shape of the cardboard 18," be- Qing the same as the size and shape of the fin- ,ished package.

After the cardboard 18, has been placed in psitionon top ofthe food particles, the remaining corners' or sides of the wrapper 10, arefolded over and pulled tightly to lie fiat on the sheet 18., thus completely enclosing the food particles. The last-men` ioned cornersl or sides may be secured tothesheet 18, in one of several ways in order to seal the package, however, I have foundthe following method for securing the saidcorners to said sheet to be the-mostpractical.

lI provide .a label or seal 19, said label being the sheet 18, and over the folded over corners as shown in Fig. 7. This seal is adapted to secure the corners of the wrapper 10, to the stiff sheet 18, and to thus seal the package.

This seal or label may be' of any desired shatpe or size, but is preferably the same size as the sheet 18, and may be rovide'd on the outer side thereof with suita le advertising matter or the like. The finished packagemay then be lifted out of therecess 12, in its fully lassembled-condition. To aid in lifting the vided adjacent the recess 12, for'receivin the ear or extension 20, as shown in the drawings.

The corneror side 17, which is disposed between the food particles and the inner face of the cardboard 18, is adapted to bepulled out when lit is desired to get to the contents of the package, and as is apparent from an inspection of Fig. 9, of the drawings, said corner is adapted to assist inl dispensing the contents `from the package, said corner actin as a trough or apron over which the foo particles are adapted to pass.y

It will of course be -understood that where packagesof different shapes are desired, the wrapper will be correspondingly varied.

While I have shown one way in which the I invention may be carried out,it will be readily understoodtliat the principles of the in' 4vention may be utilized in other ways and through other forms of mechanism than those suggested herein, the selection of a specific embodimentbeing determined more particularly bythe exigencies of use or the particular wishesof the user, and I reserve the right to make all such changes in and adaptations of the construction of my invention as fairly fall` Within the scope of the accompanying claims when broadly construed.A v
